Millimeter-Wave Multi-Way Power Combining Techniques

Speaker: Qing-Xin Chu
Affiliation: South China University of Technology

Abstract: It is necessary to combine power from multiple monolithic-microwave integrated-circuits (MMICs) to obtain the desired power levels because the output power from an individual solid-state device is often not enough at microwave and millimeter-wave frequencies. In this talk, common power combining techniques are introduced such as circuit-lever combining and space-lever combing. Several compact broadband millimeter-wave combiners are proposed including multi-way tree-type combiners, traveling-wave power combiners, and radial power combiners. The proposed combiners demonstrates the characteristics of compact, broadband, and low insertion loss, which are good candidates for millimeter-wave power combing amplifiers.
